Geometry, Grade 4 Workbook by Maria Miller (2016)

We start Geometry, Grade 4 Workbook by reviewing the concepts of area and the perimeter of rectangles (third grade topics). Students get to apply these concepts in problem solving, including problems where they write simple equations and explore possible perimeters for a given fixed area. The focus of this workbook is angles. Students learn about lines, rays, and angles, and about acute, right, obtuse, and straight angles. Next they learn how to measure and draw angles with a protractor. We also study angle problems where students write simple equations, and estimate some common angles. The lesson Parallel and Perpendicular Lines ties in with the topic of angles, because perpendicular means “to be at a right angle.” Next we study parallelograms and other quadrilaterals in more detail, paying attention to the angles and side lengths in them. We study triangles, and classify them according to the angles. The last topic for this workbook (an easy one) is line symmetry. The study of geometry is full of strange-sounding words to learn. I encourage you to let the student(s) keep a geometry notebook , where they will write every new concept or term, and draw a picture or pictures and text to explain the term. The students could also do the drawing exercises from this workbook in the notebook. It will then become their very own geometry book, and while working with it, it helps them to learn and remember the terms and concepts better.
